Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research is to investigate if a 12-week program of stimulation assisted activities can combat disuse atrophy for individuals diagnosed with knee osteoarthritis (KOA). This study will use a home-based medical device to administer electrical stimulation and measure its effect on outcomes that include quadriceps strength, perceived functional capacity, pain, and walking performance. It was hypothesized that stimulation assisted activities will show larger muscle mass and strength improvements; improved gait kinematics, pain and perceived function; and a high compliance to the assigned program compared to no stimulation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study aims to evaluate the Cionic Neural Sleeve for subjects diagnosed with KOA. All participants will be assigned a Cionic Neural Sleeve to wear on the most impacted leg and be prescribed a home-based exercise and walking program. Participants will be randomly assigned into three groups: (a) control; (b) neuromuscular electrical stimulation (NMES); (c) NMES and functional electrical stimulation (FES). The control group will not receive stimulation for the exercise and walking program, whereas participants in the NMES group will receive stimulation during exercises, and participants in the NMES and FES group will receive stimulation during exercises and walking. The primary outcome measures include quadriceps strength and perceived pain. Exploratory outcome measures include adherence to the program, thigh muscle volume, functional ability of the lower limb, walking performance, perceived functional capacity, and perceived quality of life.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

Device: Cionic Neural Sleeve NS-100. Participants will wear the device during the 12-week exercise and walking program. There will be no stimulation.

Group Type OTHER

12-week exercise and walking program

Intervention Type OTHER

The exercise program requires isometric quadriceps contractions in a supine position with a rolled-up towel placed behind the knee. The exercise program will be performed by participants 5 days per week for 12 weeks. The walking program will be performed 3 days per week for 12 weeks. Participants will walk for 10 minutes and then gradually increase walking time to 30 minutes by the end of the study. Participants will wear the device during the exercise and walking program, which may range from 1 minute to 35 minutes per day.

NMES

Device: Cionic Neural Sleeve NS-100. Participants will wear the device during the 12-week exercise and walking program and receive stimulation assistance during the exercise sessions.

Group Type EXPERIMENTAL

Intervention Type OTHER

The exercise program requires isometric quadriceps contractions in a supine position with a rolled-up towel placed behind the knee. The exercise program will be performed by participants 5 days per week for 12 weeks. The walking program will be performed 3 days per week for 12 weeks. Participants will walk for 10 minutes and then gradually increase walking time to 30 minutes by the end of the study. Participants will wear the device during the exercise and walking program, which may range from 1 minute to 35 minutes per day.

NMES

Intervention Type DEVICE

Sleeve applies neuromuscular stimulation during exercises to help contract appropriate muscles at appropriate times.

NMES and FES

Device: Cionic Neural Sleeve NS-100. Participants will wear the device during the 12-week exercise and walking program and receive stimulation assistance during the exercise and walking sessions.

NMES

Intervention Type DEVICE

Sleeve applies neuromuscular stimulation during exercises to help contract appropriate muscles at appropriate times.

FES

Intervention Type DEVICE

Sleeve applies functional electrical stimulation as patients walk to help contract appropriate muscles at appropriate times.
